Embodiment Construction

[0040] FIG. 1 shows an automotive part, generally designated 10 , comprising a metal plate 12 for forming a metal body and comprising a peripheral region 14 covered with a plastic body 16 . The outer boundary 18 of the metal plate 12 defines a first frontier of the peripheral area 14 , the inner boundary line of the peripheral area 14 , ie the limit of the metal plate 12 covered by the plastic 16 , is indicated by 20 . Metal plate 12 includes two opposing planes 40 and 42 that meet at outer boundary 18 .

[0041] The plastic body 16 includes a plurality of studs 22 integrally formed therewith for positioning automotive parts. Other functional elements can also be integrally formed with the plastic body 16 . In the example shown, the car part is the roof. However, the part could also be an underbody panel.

[0042] FIG. 2 shows a mold 24 according to the invention for making part 10 of FIG. 1 . The mold 24 comprises two half-moulds 26 and 28 capable of relative translation ...

Abstract

The invention relates to a mold (24) for manufacturing an automobile part (10), including a metal body (12), at least one peripheral area (14) of which is covered in a body made of plastic material, including: at least one molding cavity (30) of the plastic material body (16), defined by walls (32, 34) defining the general shape of the plastic material body (16); abutments (36, 37), projecting from the walls (32, 34), for positioning the metal body (12) at least partially remote from the walls (32, 34) of the mold (24), the abutments (36, 37) being equipped such that, when the mold (24) is in a closed position, they constrain the peripheral area (14) into a shape that, once the part (10) is manufactured, prevents the dislodging of the metal body (12) from the plastic material body by translation or rotation.

Description

technical field [0001] The invention relates to the automotive sector, in particular to the manufacture of hybrid parts (pièces hybrids) consisting of metal bodies partially covered with plastic. Background technique [0002] Known for their high strength and low manufacturing costs, metals are widely used in the automotive industry to make parts such as hoods or underbody panels. [0003] In addition, metal parts can also be partially overmolded (surmouler) to strengthen, prevent corrosion or provide additional functions, such as fixing functions. [0004] Document US 2007 / 0131012 discloses a method for the manufacture of automotive parts by inserting a peripheral region of a metal body into a mold cavity and then injecting thermoplastic material into the mold so as to form around the peripheral region of the metal body Plastic body. This results in a hybrid part consisting of a metal body partially covered with plastic at the periphery. [0005] This method has the disa...
